Characteristics and Advantages of Sanding Belt Elastic Grinding

Sanding belt grinding is a kind of elastic contact grinding, even under the condition of using inelastic steel contact wheel. The base material and binder of sanding belt both have certain elasticity, and in most cases, operators will choose contact wheel with elastic rubber.

On one hand, sanding belt grinding not only has similar functions with grinding wheel, such as plough and cutting, but also can compress the workpiece surface by abrasive grains. What’s more, it can make plastic deformation, variations of chilled layer and thermoplastic flow by rubbing contact surface. Therefore, from this point of view, sanding belt grinding has multiple functions, such as grinding, lapping and polishing, which are the reasons that sanding belt has great grinding surface quality.

On the other hand, the elastic grinding characteristics of sanding belt can make sanding belt have longer contact length with workpieces than grinding wheel in grinding area, and at the same time, the more abrasive grains there are, the smaller load single abrasive grain will bear.

The abrasion ratio of  sanding belt (The ratio between grinding material removal amount and the consumption of sanding belt abrasive grain is called grinding ratio, and the reciprocal of grinding ratio is called the abrasion ratio) is much smaller than that of grinding wheel.  If you want to learn more details about sanding belt and other coated abrasives, please visit  Nanchang Dove Industrial Materials Co., Ltd. and Zhengzhou Feilaike Abrasive Materials Co., Ltd. that are both professional coated abrasives manufacturers in China.
